A DNA Match Proves Presence, Not Guilt: Supreme Court Upholds Acquittal in 2011 Double Murder Case

Case at a glance: The Supreme Court has dismissed the State's appeal against the acquittal of a woman accused of murdering her stepmother and minor half-brother in 2011. Accepting that DNA from a blood stain matched the accused, the Court held that this showed only that she was present in the house at some point in time, not on the date of the alleged crime, and that the prosecution's chain of circumstances was incomplete.

On 7 September 2011 police found two bodies in a locked house at Diur: Mithilesh Kumari and her minor son Bhupinder Singh. The autopsy showed strangulation, with death five to seven days earlier. The prosecution alleged that the accused, Anchla, the woman's stepdaughter, killed both on 31 August 2011.

The case was circumstantial: last-seen evidence from a taxi driver and a hotel worker, a bleeding thumb injury, and DNA matching her blood to a stain in the house. The High Court acquitted her and the State appealed.

The Key Question Before the Court

Was the prosecution's chain of circumstances, including DNA evidence, complete enough to establish the accused's guilt beyond reasonable doubt?

Why the DNA Match Was Not Enough

As reported, the Court accepted the forensic match but noted that only one sample, a scrape from a trunk, yielded good-quality DNA and the others were degraded. The match therefore showed only that she was present at some point in time, not on 31 August 2011. She was a regular visitor to the house, and her blood was not found on the victims' clothes or on any ligature.

The Court also treated the taxi driver and hotel worker as witnesses set up to create evidence, since police never disclosed how they were identified, and noted that the last-seen witness improved his account only in court. Failure to collect call detail records with tower locations was called a serious investigational lapse, and the identity of the lock was not established. It upheld the acquittal.

What the Court Actually Held

• The State's appeal against acquittal was dismissed; guilt was not proved beyond reasonable doubt.
• The DNA match showed presence at some point in time, not on the date of the crime.
• Doubts about last-seen witnesses and the absence of call detail records weakened the chain of circumstances.
• A control sample from the cabinet was not examined and samples were collected and compared several days after the discovery.

Why This Judgment Matters

• It is a clear illustration that scientific evidence must be tied to the time and manner of the offence.
• It underscores the importance of sample handling, degradation and control samples in forensic evidence.
• It treats investigational gaps, such as missing call records, as weighing against the prosecution.
• It shows the Court's cautious approach to interfering with an acquittal where another view is possible.

What Should Advocates Take Away From the Judgment?

For Defence Counsel

• Press on the gap between a DNA match and the time of the offence, especially where the accused had lawful access to the premises.
• Challenge sample preservation, chain of custody, degradation and unexamined control samples.

For Prosecutors

• Collect call detail records, disclose how witnesses were identified, and tie forensic findings to the time of the offence.
• In appeals against acquittal, expect the Court to ask whether the High Court's view was perverse or the only possible one.
